You need to use IMG TOOL 1.3. With IMG TOOl, open gta3.img(program files>Rockstar games>GTAIII>models).
Go to Edit>find. Type in player.dff. Use Command>rename, and rename the player.dff to player.dff.bak. Now,
use Command>Add, and and my player.df
Copy and paste the skins into the gta vc directory.
i have included a bmp, that has 4 watches on it, each none has a time written on it, (1985, 1955,1885,2015) transfer these to marty's skin if wanted to.
DO NOT EDIT THESE SKINS WITHOUT MY PEM
